ClearMicroplastics in the environment: A DPSIR analysis with focus on the responses
This review applies a DPSIR (driving forces, pressures, states, impacts, responses) framework to organise current knowledge on microplastic pollution, covering sources, distribution across environmental compartments, and socio-economic impacts. The authors assess available response strategies including regulatory instruments, biodegradable plastics development, wastewater treatment, and environmental cleanup, while identifying key gaps in the literature.
The Environmental Impact of E-Waste Microplastics: A Systematic Review and Analysis Based on the Driver–Pressure–State–Impact–Response (DPSIR) Framework
This systematic review examines microplastics that come from electronic waste like old phones and computers. E-waste microplastics are particularly concerning because they can carry toxic metals like lead and flame retardants. These contaminated particles enter the soil near disposal sites and can work their way into the food chain, potentially affecting gut health and overall well-being.
Re-imagining the driver–pressure–state–impact–response framework from an equity and inclusive development perspective
This paper critiques the widely used DPSIR environmental policy framework for overlooking social justice and equity, arguing that environmental burdens fall disproportionately on vulnerable communities. The critique is relevant to microplastic pollution, which often affects lower-income and coastal communities most severely.
Beach pollution from marine litter: Analysis with the DPSIR framework (driver, pressure, state, impact, response) in Tuscany, Italy
Researchers applied the DPSIR environmental analysis framework to understand the accumulation of litter and waste on beaches in Tuscany, Italy, finding that coastal ocean currents — not local waterways — were the main source of beach debris, while local sewage contaminated the sand with fecal bacteria at levels posing moderate health risks. The study demonstrates how a systems-level approach can help beach managers identify the true causes of marine litter and evaluate the effectiveness of existing cleanup measures.
The Marine Plastic Litter Issue: A Social-Economic Analysis
Using the DPSIR framework, this study analyzed marine plastic litter pollution as a social-economic issue, finding that fewer than 10 peer-reviewed studies had applied this policy-relevant analytical model to ocean plastics, and identifying management response gaps in food security, transport, and shelter contexts.
Upcycling Microplastic-Laden Spent Adsorbents to Mitigate Secondary Pollution: Insights into the Drivers, Pressures, State, Impacts, Responses (DPSIR) Framework
When microplastics are removed from water using adsorption materials, the resulting plastic-laden spent adsorbents create a secondary waste problem. This study applied the DPSIR (Drivers-Pressures-State-Impacts-Responses) environmental management framework to this issue and tested whether pyrolyzing spent adsorbents at 600°C could convert them into useful circular carbon materials (CCM) while destroying the embedded microplastics. The pyrolysis approach achieved about 60% polystyrene microplastic removal and produced a porous carbon material with useful surface properties for further water treatment. The work highlights that microplastic remediation technologies need to account for their own waste streams to avoid simply shifting pollution from one form to another.
How natural and anthropogenic factors should drive microplastic behavior and fate: The scenario of Brazilian urban freshwater
This review examines the factors driving microplastic contamination in Brazilian freshwater systems, including the country's massive plastic production and limited recycling infrastructure. Researchers highlight that more than half of post-consumer plastic packaging in Brazil goes unmonitored, and most microplastic research has focused on marine environments while freshwater data remains scarce. The study calls for more systematic monitoring of Brazilian rivers and lakes, especially given the country's continental-scale waterways and diverse ecosystems.
Penerapan kerangka kerja DPSIR terhadap sampah dan dampaknya pada lingkungan di Kawasan Wisata Pantai Pangandaran
This paper is not relevant to microplastics research; it analyzes waste management and environmental impacts at Pangandaran Beach in Indonesia using the DPSIR framework, focusing on general solid waste rather than microplastic pollution specifically.
Contamination by plastics and microplastics: (re)knowing the lived reality.
This Brazilian literature review examines the environmental impact of plastics and microplastics across different pollution scenarios, discussing the history of plastic production and consumption, relevant environmental legislation, and the importance of recycling in addressing plastic contamination.
The way of microplastic through the environment – Application of the source-pathway-receptor model (review)
This review applies the Source-Pathway-Receptor model to organize current knowledge about how microplastics move through the environment. The authors found that while more studies on environmental microplastic concentrations are being published, a comprehensive risk assessment remains impossible due to gaps in understanding transport processes. The study provides a methodological framework to help guide future research and risk assessments for microplastic pollution.
Microplastics in marine ecosystems: Sources, effects, and mitigation strategies
This review examines the sources, environmental pathways, ecological impacts across trophic levels, and mitigation strategies for microplastic pollution in marine ecosystems, synthesizing current evidence on biological harm and evaluating policy frameworks, technological solutions, and individual behavioral changes aimed at reducing marine microplastic loads.
Microplastic Sources, Reduction and Remediation: Current State and Future Trends
This review synthesizes current knowledge on primary and secondary microplastic sources, methods for eliminating microplastics from different environmental media, and the role of circular economy principles in minimizing microplastic pollution across the entire plastic value chain. The study outlines an upside-down pyramid strategy prioritizing prevention, reduction, reuse, and recycling over disposal, and surveys emerging technologies for sustainable polymer production and remediation.
Impactos clínicos, sociais, tóxicos e ambientais causados pela exposição contínua e sistêmica de microplásticos no ecossistema brasileiro
This Brazilian review examines the clinical, social, toxic, and environmental impacts of continuous systemic microplastic exposure in the Brazilian ecosystem, noting that 8.3 billion tons of virgin plastics have been produced globally. The authors discuss how plastic fragmentation into microparticles threatens Brazilian biodiversity, food safety, and human health through multiple exposure pathways.

Challenges on environmental regulation and monitoring of microplastics: the case of the State of São Paulo (Brazil)
Researchers examined the challenges of developing standardised regulatory frameworks and monitoring programmes for microplastics in Brazil, using the State of Sao Paulo as a case study and describing the role of the HydroPoll Network in facilitating science-policy interaction. The study identified key barriers to reproducible long-term monitoring including the lack of harmonised sampling, analysis, and reporting protocols, and proposed a framework for bridging scientific evidence and environmental regulation.

Macroplastics in the Guarapiranga reservoir (São Paulo, Brazil): estimating the generation of microplastics
Researchers surveyed macroplastics in the Guarapiranga Reservoir, a major public water supply in Sao Paulo, Brazil, and estimated the rate of microplastic generation from their fragmentation. Large plastic debris in the reservoir was found to be a significant in-situ source of secondary microplastics.
